,'Iiivot V engages the 'steelyard -mediate lever N, is su can! Y 'imparted to form 'kn1"e edge pivots, and S is the central pivot 'for connecting Withthe platform lever, (not shown). The Weighty and beam actuating arm T is olf-set t'vex" tend through the olf-set portion C of the' scale frame and i ends of which are.the lknife edge pivots V and V', the former of tli'e'sepvts isnt-fA- tachedl to the steelyard M -or-other actuating 5. device for the lieXible Atape l While the With the construction described'in op-V erationthe/niovement imparted to the tape through the long leverage'of the platform lever and the multiplication of theV interi?i iicient to -ec'tuatefthe pendulum weight F and the index Gr to the limit of movement and without an undesirable degree of multiplication in the camv pulley I. In other words, this pulley 1 may be made of larger diameter and consequently is more accurate `in its yoperation' than where a lesser degree of movement is the tape H. On the other hand, the steelyard K being attached to the lever L much nearer' its fulcrum and being unprovidedv with any intermediate multiple mechanism, will impart a comparatively small degree of movement to the beam J so that the angular movement of the. latter is not excessive.

lVhat l claim as my invention is.:

l. In a scale, the combination of a pendulum'weight, a beam, a platform, a platform lever having an arm for actuating said pendulum weight and beam, cdiinections between said pendulum weight and arm, and connections between the latter and the beam, said connections respectively engaging said arm at separated points, whereby the movement of the weight actuating connection is greater than that of the beam actuating connection.

2. ln a scale, the combination of an angularly movable member provided with a pendulum weight and an index, a platform lever, a verticallyfextending connection for singularly operating said member, abeam extending on opposite sides of said vertical connection, a horizontal lever, l actuating means operatively connecting said vertical connection and said lever, land. a separate connection Jfrom saidbeam to said platform lever engaging thev latter at a .point nearer its fulcrum than the point ofl engagement with the actuating means forsaid vertical connection. y Y f 3. ln asc'al'e, the combination'o an'allegri'-` larlyy movable member having pendulum" weight and an index attached thereto, a vertically-extending connectingmeans engag. ing said member to 'actuate the same, a beam, a platform lever, yand actuating?s means lop'- eratively connecting 'the vertically-extending coperating "connection between said beam end said plat'- nearer its fulcrumi at its outer end has the' in-M validly Offset Portion Ui at the opposite-c,
